My Hero Academia: Thunder God

"Does thirteen have a Quirk similar to Eraser Head's?" the purple-black energy entity mused aloud, watching the teachers and students in the distance. His voice dripped with a sinister calm.

"According to the schedule we intercepted a few days ago, All Might should be here by now."

Aizawa's expression grew more serious. The situation was turning more dire by the minute, especially with All Might's absence. He began to suspect that they were in for a far greater challenge than anticipated.

"They must've made good use of the information they stole," Aizawa muttered, feeling a knot of dread forming in his chest. The villains were too prepared.

"Teacher, you're not forgetting about us, right?"

Kaminari's voice cut through the tension as he stared at the approaching swarm of villains with a determined smile. "We might not be able to take down the big boss, but we can definitely handle the minions!"

His words weren't just bravado, they were practical. Kaminari knew his limits. The head-to-heads with the main villain were meant for someone like Aizawa or, ideally, All Might. But dealing with the grunts? That was something they could handle.

"Although you're usually annoying, I have to say… not bad today!" Bakugo grinned viciously, small explosions popping from his hands as he eyed the villains. "Invading U.A. is the dumbest thing these idiots could do!"

Kirishima and Tetsutetsu, both hardening their bodies in sync, shared a knowing look. Their Quirks made them ideal for crowd control. A swarm of weaker villains was the perfect challenge to test their mettle.

But just as they were preparing to charge in, Aizawa shut down their excitement with a cold dose of reality.

"Get back!"

"What?!" Kirishima blurted, stunned.

"You're not ready for this fight."

Aizawa's voice was firm. He glanced at Kaminari, knowing the student was headstrong, but he couldn't afford to let them get ahead of themselves. "Don't even think about fighting right now. Use your Quirks to contact the outside world. That's your priority."

"Huh?" Momo asked, confused. "Shouldn't the school's alarm system have gone off by now? Wouldn't they already know about the intruders?"

Thirteen looked up at the ceiling, visibly troubled. "The alarms… they should have been triggered by now."

"Something's interfering," Todoroki deduced, his eyes narrowing as he stared at the villains below. "They must have someone whose Quirk is jamming the sensors."

Kaminari's face darkened. "It's more than that," he muttered grimly. "I've been trying to send out a signal with my communicator since the attack started, but it's being blocked. There's another wave covering the area, jamming all radio signals."

"That means someone among the villains is using an electricity-based Quirk to block communications," Kaminari continued. "And they're good at it, better than me, for sure."

He clenched his fists, frustration simmering beneath the surface. "If it's just another electricity user, I can deal with them. But if they're leagues above me in every way… we're in serious trouble."

Aizawa frowned, his usual calm now strained. He processed Kaminari's assessment quickly. "So, we're on our own for now," he thought, knowing they couldn't rely on backup.

He turned to Thirteen. "Get the students to safety. Then, find a way to contact the school."

"Understood, but what about you?" Midoriya asked, concern evident in his voice. "You can't take on that many villains alone! Your Quirk only works when you can erase theirs, but in a fight like this…"

Kaminari chimed in, "Yeah, sensei, you should let us help handle the smaller fry. You can't take on all of them at once by yourself."

Aizawa paused for a moment, as if considering their words. But then, he gave a sharp reply: "Remember, having one strong Quirk doesn't make you a Hero."

Without another word, Aizawa removed the bandages from his neck, his sharp eyes narrowing as he sprinted toward the growing horde of villains. His parting words echoed back to the students:

"This is the domain of Heroes. I'll leave the rest to you, Thirteen"

Kaminari's lips curled into a smirk. Aizawa hadn't explicitly allowed them to fight, but his message was clear: U.A. students had the right to use their Quirks freely on campus. And now, they were facing villains. This was no longer a classroom lesson. This was real.

"Good," Kaminari murmured. "Let's do this."

In the distance, Aizawa dove into the mob of villains with remarkable precision, neutralizing their Quirks one by one. His movements were fluid, calculated, a perfect example of a Pro Hero in action. The enemies fell before they even realized what was happening.

"Whoa…" Kaminari whispered in awe, watching their teacher dismantle the group. "So this is the strength of a Pro Hero..."

The others weren't far behind in their excitement.

"Alright!" Bakugo growled, sparks flying from his hands. "It's time to crush these bastards!"

Kirishima and Tetsutetsu were practically buzzing with energy, eager to dive into the action. They didn't notice, however, that some of their classmates like Mineta were pale with fear, frozen at the thought of facing real villains.

Kaminari, sensing the tension, approached the more nervous students with a calm smile. "Don't worry. I'm here with you."

"Thanks, Kaminari…" Kyoka and Momo, though still on edge, visibly relaxed at his words. Having someone exude confidence in a crisis did wonders to ease their nerves.

Just as Bakugo and the others prepared to charge into battle, the ground beneath them darkened, and a swirling vortex of purple-black energy suddenly erupted, enveloping everyone in its path.

"What the hell is this?!" Tetsutetsu shouted, scanning the ominous energy field.

"Nice to meet you."

The voice was polite, almost disturbingly so. A human-like figure made of purple-black energy appeared before them, introducing himself in an unnervingly calm tone.

"We are the League of Villains."

The figure continued as if this were a casual conversation. "We apologize for our abrupt visit to U.A. High. Our mission is simple: we're here to kill the 'Symbol of Peace,' All Might."

While the villain monologued, Kaminari's mind was racing. He was scanning the vortex for any weaknesses. Every Quirk, no matter how powerful, had its limits or flaws. The trick was finding them.

"If only I could test this guy with a good jolt of electricity…" Kaminari thought, frustrated. But there were too many of his classmates around. He couldn't risk hurting them in the process.

"Where does this guy get off talking so much?!" Bakugo's patience finally snapped. Without warning, he launched himself at the villain, his hand igniting in a violent explosion aimed directly at the figure's head.

"Boom!"

Kirishima and Tetsutetsu followed suit, charging in right behind Bakugo. A hardened hand chop from Kirishima and a steel kick from Tetsutetsu slammed into the villain's form, sending ripples through the purple-black energy.

"Got him?" Kaminari asked, shielding his face from the smoke and debris.

But from within the smoke, the villain's voice echoed again calm, almost amused.

"So dangerous, so dangerous!" the villain laughed. "You students have incredible potential."

The figure remained intact. Kaminari's stomach dropped as he realized the attacks had done nothing.

"He's immune to physical damage?" Kaminari thought, his fingers tightening around the coin he was holding. "Is this guy some kind of energy being?"

His mind flashed back to the Logia-type Devil Fruit users from the anime "One Piece." If this villain was anything like that, it would make things much more complicated.

Before Kaminari could process it fully, the villain moved again. The dark energy around him began to expand, growing more volatile. The sheer volume of energy created a wave-like force, far too much for Thirteen to absorb all at once.

"My mission is to scatter you and kill you one by one!" the villain declared, his energy surging forward.

"Everyone, watch out!" Thirteen shouted, but it was too late. The wave of energy was too powerful to stop, and in the blink of an eye, Kaminari and his classmates were swallowed by the vortex.

"Gotcha!" Kaminari acted on instinct, grabbing hold of Kyoka and Momo's hands. He pulled them close as the world around them twisted and warped.

Then, as quickly as the energy had enveloped them, the vortex dissipated. Sunlight streamed back into the space, but something was horribly wrong.

Iida and Thirteen looked around in horror.

"Everyone… they're gone."
